NEW YORK (AP) — Police and firefighters are at the scene of an apparent explosion in New York City, and authorities say 25 people suffered minor injuries.

Police spokesman J. Peter Donald said on Twitter that the explosion happened at about 8:30 p.m. Saturday on West 23rd Street in the Chelsea section of Manhattan. He says several people were taken to hospitals with injuries. The Fire Department tweeted that none of the injuries appear to be life-threatening.

No detail about the extent of damage was immediately available.

Chris Gonzalez, visiting from Dallas, was having dinner with friends at a restaurant. The 26-year-old says she heard and felt a blast. She said the restaurant went quiet.

Witnesses say FBI and Homeland Security officials are also at the scene.

The reports of a possible blast come hours after a pipe bomb exploded in Seaside Park, New Jersey, shortly before thousands of runners participated in a charity 5K race to benefit Marines and sailors.
